Locus	Cultural Requirements	Link Group	Type
pdx-1	IVR. Right of pyr-1 (<1 to 10%). Left of T(S1229) and pt (2%) (40, 55, 692, 808). (482) Uses pyridoxine, pyridoxal, or pyridoxamine (843, 845, 846). Shows intralocus complementation (845, 846) and recombination (848), Provided the first proven example of gene conversion (686). Scoring is sharpened by addition of 100 mg of desoxypyridoxine per liter (845). Several alleles (called pdxp: e.g., 44602) are pH sensitive and can grow without pyridoxine on medium containing ammonium ions at a pH above 6 (1029). Conidia are subject to death by unbalanced growth on minimal medium (1033). A yellow pigment is excreted under certain conditions by the pdx-1;En(pdx) double mutant; see En(pdx). Allele 44204 originally called pdx-2 (see reference 848).	IVR	B
sc	IIIR. Between the centromere and ser-1 (504). Linked to thi-4 (1/280) and spg(0 + + /179); right of acr-2 (3 to 6%) (498, 814). Irregular flat spreading growth with knobby protrusions but no conidia. Mycelium usually appears yellowish rather than orange. Female fertile. Homozygous sc x sc crosses give nonlinear asci (827, 828, 1011). Cell wall analysis (132). Reduced amount of cell wall peptides (1165). Allele R2503 called col-14; allele R2386 called smco-2 (382). For modifier, see mod(sc).	IIIR	B
